basic.swift

// Basic.swift
func setTimeout(delay:NSTimeInterval, block:()->Void) -> NSTimer {
    return NSTimer.scheduledTimerWithTimeInterval(delay, target: NSBlockOperation(block: block), selector: #selector(NSOperation.main), userInfo: nil, repeats: false)
}

func setInterval(interval:NSTimeInterval, block:()->Void) -> NSTimer {
    return NSTimer.scheduledTimerWithTimeInterval(interval, target: NSBlockOperation(block: block), selector: #selector(NSOperation.main), userInfo: nil, repeats: true)
}

Simple usage:

// Simple usage
let handle = setTimeout(0.35, block: { () -> Void in
    // do this stuff after 0.35 seconds
})

// Later on cancel it
handle.invalidate()
